Description

Technical Field

[0001] This utility model relates to the field of therapeutic electrode technology, specifically an inflatable cavity therapeutic electrode. Background Technology

[0002] Pelvic floor dysfunction (PFD) is a group of diseases caused by various factors leading to abnormal pelvic organ function, including vaginal laxity, stress urinary incontinence, and other functional disorders. Cavity therapy or rehabilitation typically involves inserting therapeutic electrodes into the patient's pelvic cavity. Currently, most commercially available therapeutic electrodes have a fixed size and cannot be matched to patients with pelvic cavities of different sizes. A few therapeutic electrodes have adjustable sizes, but the sealing of the circuitry cannot be guaranteed during electrode size adjustment. Due to the special environment of pelvic floor treatment, insufficient circuit sealing can affect the normal use of the therapeutic electrode. Therefore, a therapeutic electrode is needed that allows for size adjustment without affecting the circuitry. Utility Model Content

[0011] Furthermore, the air tube includes a sleeve and an air nozzle; the air nozzle is installed inside the sleeve and communicates with the concave area of ​​the keel to form an air passage; the sleeve is located inside the electrode cap and is gap-fitted with the electrode cap to engage the opening ends of the inner layer and the outer layer.

[0030] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0031] Please see Figure 1This embodiment introduces an inflatable cavity treatment electrode, which mainly includes an electrode cap 4, an airbag frame 3, an airbag 1, an electrode module 2, an electrode circuit board 6, and an end cap 7.

[0032] The electrode cap 4 is shaped like a hat. The end connected to the sleeve 321 of the airbag frame 3 has a small diameter, and the diameter gradually increases along its axial direction, which plays a certain role in blocking and limiting, and controlling the length of the electrode in the pelvic cavity.

[0033] Please see Figure 4 and Figure 5 The airbag frame 3 is mainly composed of a keel 31 and an air tube 32. The keel 31 and the air tube 32 are integrated. The keel 31 is mainly composed of side plates 311, baffles 312, and reinforcing ribs 313. The side plates 311 are mainly U-shaped, with their ends integrated with the air tube 32. The baffles 312 are horizontally installed in the middle of the side plates 311, dividing the frame formed by the side plates 311 and the air tube 32 into upper and lower parts, forming the concave area of ​​the keel 31. Although the outer wall of the air tube 32 and the side plates 311 enclose a closed frame, the interior of the air tube 32 is connected to the concave area of ​​the keel 31. To further stabilize the relationship between the side plates 311 and the baffles 312, reinforcing ribs 313 are provided between the side plates 311 and the baffles 312, that is, reinforcing ribs are provided in the concave area of ​​the keel. The shape of the reinforcing ribs 313 can be triangular, rectangular, etc. Figure 4 or Figure 5 The image shows a grid-like distribution of reinforcing ribs 313.

[0034] In practical applications, the side plate 311 and the baffle plate 312 can be integrally formed, directly creating symmetrical concave areas after forming.

[0035] The air tube 32 mainly consists of an air nozzle 322 and a sleeve 321. The air nozzle 322 is installed at the center of the sleeve 321, and the diameter of the sleeve 321 is smaller than the diameter of the electrode cap 4. Since the airbag 1 is fitted on the outer surface of the airbag frame 3, and the keel 31 has a relatively symmetrical concave area, gas enters the concave area of ​​the keel 31 through the air nozzle 322, forming an air passage.

[0036] Please see Figure 3The airbag 1 has an inner layer and an outer layer. The inner layer is placed inside the outer layer, with one end along its length sealed to the outer layer, and the other end open to both. The outer layer has one or two symmetrical recesses, with a wiring hole at the bottom of each recess communicating with the inner layer. The gap between the inner and outer layers forms a wiring cavity. The curved end of the keel 31 enters the inner layer of the airbag 1 from the open end of the inner layer to support the airbag 1. The recess of the outer layer of the airbag 1 faces the concave area of ​​the keel 31. The electrode module 2 engages within the recess to achieve a detachable wiring connection. The gap between the outer and inner layers of the airbag 1 forms a wiring cavity, which communicates with the recess through a wiring hole. The wiring of the electrode module 2 passes through the wiring hole and wiring cavity of the airbag 1 and is located within the electrode cap 4.

[0037] The inner and outer openings are the openings of the airbag 1. The openings of the airbag 1 are sealed by the electrode cap 4 and the sleeve 321. Limiting protrusions are provided at the inner and outer ends of the airbag 1, respectively engaging with the electrode cap 4 and the sleeve 321. The end of the airbag 1 is located within the gap between the electrode cap 4 and the sleeve 321. The end of the airbag 1 fills the gap, and then the sleeve 321 and the electrode cap 4 engage to seal and fix the opening of the airbag 1. However, the internal space of the airbag 1 is connected to the interior of the electrode cap 4.

[0038] The sleeve 321 and the electrode cap 4 can be locked together to seal and fix the end of the airbag 1, allowing the end of the airbag 1 to communicate with the outside world or other objects through the internal space of the sleeve 321 and the electrode cap 4. The sleeve 321 and the electrode cap 4 can be locked together by snap-fit, bolted, or a combination of snap-fit ​​and bolt. However, the connection between the two is detachable. To accommodate the inflation of the airbag 1, the middle of the airbag 1 is horizontally concave to form a fold. The overall shape of the fold area is U-shaped and parallel to the receiving groove. In accordance with the shape of the keel 31, the fold area is located in the middle, which can accommodate the electrode module 2 whether it is placed in one or both receiving grooves of the keel 31.

[0039] Please see Figure 6 and Figure 7 Electrode module 2 includes electrode components, a base 26, and a flexible flat cable 25. The electrode components mainly consist of an electrode housing 21, a sealing gasket 22, electrode plates 23, and screws 24. The electrode housing 21 has holes for accommodating the electrode plates 23. The tail ends of multiple electrode plates 23 pass through these holes to the other side of the electrode housing 21. A sealing gasket 22 fills the gap between the electrode plates 23 and the electrode housing 21. The electrode plates 23 are mounted on the flexible flat cable 25 using screws 24. The shape of the flexible flat cable 25 is adapted to the airbag 1 and the airbag frame 3, and due to the limitations of its material, it can accommodate the inflation of the airbag 1. Electrical signals are transmitted from the flexible flat cable 25 to the electrode plates 23 via the screws 24.

[0040] The base 26 is located at the bottom of the electrode housing 21, and the two are sealed together by a sealing ring 27. The electrode housing 21 is engaged in the receiving groove of the airbag 1. This engagement can be achieved by either a protrusion inside the receiving groove and a groove on the surface of the electrode housing 21, or a recessed portion in the receiving groove and a protrusion in the electrode housing 21. Alternatively, glue can be used for further fixation to fill any gaps between the two. The base 26 has a through hole that connects to the wiring cavity via a wiring hole. The flexible flat cable 25 serves as the wiring for the electrode module 2. It passes through the through hole in the base 26, through the wiring hole, into the wiring cavity, and then through the gap between the inner and outer layers of the airbag 1 to enter the electrode cap 4.

[0041] The electrode circuit board 6 is located inside the electrode cap 4 and is electrically connected to the flexible flat cable 25. The electrode circuit board 6 can be installed inside the electrode cap 4 using bolts or other methods, or an end cap 7 can be provided. The end cap 7 is bolted or snap-fitted to the electrode cap 4 to limit the electrode circuit board 6, ensuring it is positioned within the gap between the end cap 7 and the electrode cap 4. Alternatively, bolts and the end cap 7 can be used together to secure the electrode circuit board 6. The end cap 7 is installed at the end of the electrode cap 4 facing away from the airbag 1, preventing the electrode circuit board 6 from being exposed and facilitating connection to other devices.

[0042] A connecting pipe extends from the center of the end cap 7 along the direction of the air nozzle 322, and is fitted onto the end of the air nozzle 322 located inside the electrode cap 4. The gap between the connecting pipe and the air nozzle 322 is sealed by an O-ring 5. The air supply component (e.g., an air pump) is connected to the connecting pipe at the center of the end cap 7. Therefore, the air path of the airbag 1 and the wiring of the electrode module 2 are separate and do not interfere with each other. It should be noted that since both air inlet and outlet are through the air nozzle, the air supply component also has corresponding venting measures, such as an exhaust valve, which is installed on the pipeline between the air supply component and the air nozzle via a tee to allow both air inlet and outlet.

[0043] In practical applications, the airbag 1 can have a receiving slot on one side or symmetrically on both sides. The connecting pipe between the air pump output end and the end cap 7, and the air passage of the airbag frame 3 are connected to the inner cavity of the airbag 1 for inflating or deflating the airbag 1. When the air pump inflates, the airbag 1 expands, pushing out the electrode module 2, thus changing the diameter of the electrode to accommodate the larger diameter of the pelvic floor cavity. Because the gap between the electrode module 2 and the airbag 1 is tight, the change in the diameter of the electrode will not affect the wiring. The degree of inflation of the airbag 1 can be determined by monitoring the air pressure of the airbag 1, thereby ensuring the patient's comfort.

[0044] After the treatment electrodes are assembled, they are inserted into the patient's pelvic floor cavity. An air pump inflates the airbag 1 to the appropriate size, allowing the electrode pads 23 to conform to the cavity. Energy is then released from the electrode pads 23 to provide treatment. After treatment, the airbag 1 is deflated, the electrode module 2 retracts, and the electrodes are removed, completing the treatment.

[0045] Therefore, this embodiment separates and seals the air path and the chamber containing the wiring, preventing interference between them. This reduces the risk of air leakage and prevents the air path from affecting the operation of the electrode module 2. The airbag 1 and electrode module 2 are relatively independent, resulting in a simpler structure. The airbag 1 and electrode module 2 can be detached from the airbag frame 3 and electrode cap 4 for easy replacement. They can be designed for single use to minimize cross-contamination. The overall structure is simple and easy to assemble.

[0046] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
